Non-stress-connection wrapping connection type wire clamp of electric wires

Abstract

The invention discloses a non-stress-connection wrapping connection type wire clamp of electric wires. The wire clamp is composed of a wire clamp body and a fastening part assembly, the cross section of the wire clamp body is a U-shaped long groove, the fastening part assembly is transversely arranged on a U-shaped upper opening of the wire clamp body in a penetrating mode, the cross section of the position, arranged on the lower portion of the wire clamp body, of the inner wall of the U-shaped wire clamp body is in an omega shape, when the fastening part assembly is fastened, deformation of the upper opening of the wire clamp body drives the omega-shaped long groove to deform, the omega-shaped long groove deforms in an inwards-compressed mode, therefore, the two wires are tightly clenched, and firm connection between the two wires is achieved. The non-stress-connection wrapping connection type wire clamp of the electric wires is convenient to use and safe and reliable in connection.

Description

technical field [0001] The invention relates to a connection device for electric wires, which is a wire clip composed of a groove-shaped wire clip body and a fastener. It is suitable for the non-forced connection of electric wires, especially for transmission lines and distribution lines. , Tension-resistant jumper connection and "T" connection of low-voltage lines, as well as connection of substations and factory distribution power wires. Background technique [0002] At present, the power wires of power transmission and distribution lines, substations, and factory distribution are not connected under force. Parallel trench clamps and "T"-shaped clamps are commonly used. These clamps have high contact resistance and fast electrical corrosion. Burns and disconnection accidents occur frequently, which are weak links and major hidden dangers of the power grid. In the past ten years, the newly invented C-shaped wire clips, H-shaped wire clips, and wedge-shaped wire clips in th...

Problems solved by technology

[0002] At present, the power wires of power transmission and distribution lines, substations, and factory distribution are not connected under force. Parallel trench clamps and "T"-shaped clamps are commonly used. These clamps have high contact resistance and fast electrical corrosion. Burns and disconnection accidents occur frequently, which are weak links and major hidden dangers of the power grid

In the past ten years, the newly invented C-shaped wire clips, H-shaped wire clips, and wedge-shaped wire clips in the United States are intended to replace parallel groove wire clips. However, some of these wire clips still have differences in the material of the wire clip and the wire The biggest defect is that the connection becomes loose after repeated thermal expansion and cold contraction, some are expensive, and some are inconvenient to install, making it difficult to replace the parallel groove clamp
